Convert XCF to G4

The XCF (eXperimental Computing Facility) file extension is the native image format of the GIMP image-editing program. It stores comprehensive image data, including layers, channels, transparency, paths, and guides, facilitating non-destructive editing. Developed by GIMP, XCF ensures all editing information is preserved, allowing users to revert to any editing stage. While primarily used within GIMP, some other programs also support XCF files.

The G4 file extension, standing for CCITT Group 4 Fax Image, is a specialized format used primarily for storing black-and-white facsimile (fax) images. Its origins trace back to the Consultative Committee for International Telegraphy and Telephony (CCITT), now known as the ITU-T, which developed the Group 4 standard in the 1980s to improve fax transmission efficiency over digital networks. This format employs a high compression ratio to reduce file size while maintaining image quality, making it ideal for archiving documents and transmitting faxes in professional and business environments.
